Answer:
n - 6 = 5 * ( n + 2 ) ; n = -4
Step-by-step explanation:
For this problem, we will use the words to create an equation. The left hand side of the equation will be the difference of a number and 6 and the right hand side of the equation will be 5 times the sum of the number and 2. Hence, we can build the equation:
n - 6 = 5 * ( n + 2 )
If we wanted, we can solve the equation for the number, n.
n - 6 = 5 * ( n + 2 )
n - 6 = 5 * n + 5 * 2
n - 6 = 5n + 10
-16 = 4n
-4 = n
Thus, we have found the missing number to be negative four.
Cheers.
Answer:
Scale of 181: 1
Step-by-step explanation:
The first thing to do is to pass the feet by the meter, to work in the same units and thus create a consistent scale:
We know that one foot equals 0.3048 meters, therefore:
8 feet * 0.3048 meters / 1 foot = 2.4384 meters
So the scale would be:
443.2 / 2.4384 = 181.75
Which means that it is best to make a scale of 181: 1
Where 181 meters from the Empire State Building would equal 1 meter at home 0 181 inches would equal 1 inch at home
Answer:
Step-by-step explanation:
1+3+4 = 8
480 / 8 = 60
60 x 1 = 60 (concrete)
60 x 3 = 180 (sand)
60 x 4 = 240 (gravel)
60:180:240
Kelso / jones = 84.5/33.8 = 5/2 = 2 1/2
